Nexus 7 CrashingSupport

I got a Nexus 7 32GB WiFi only for Christmas and initially I wasn't having any problems with it. This is my first Android device so I wasn't sure what to expect. This past week however, it's been crashing once or twice every day. At first I had no idea what was triggering it. But then I noticed that it seemed to happen when I unplugged or plugged in headphones. It doesn't happen every time, and it's usually if I'm in an app. It tends to happen if I load a YouTube video and then unplug my headphones. Just a few minutes ago, I unplugged them when I opened Ruzzle and it froze completely, forcing me to shut it off by holding the power and volume buttons down. I was just wondering if this was a problem with the OS or my device specifically. I've factory restored it, which didn't help at all. It's running stock 4.2.1 and it is unrooted.
Also, sorry if this is the wrong area for this, new to the site.

Are you using a standard stereo headphone (without a mic.), or one with a mic? Their plugs are a little different. They are both 3.5mm in diameter but a headphone with a mic. has four conductive sections on the plug ( mic, ground, left, and right). A standard stereo headphone plug only has three conductive sections (larger ground, left, and right).

The N7 is meant to accept a headphone with a mic. If you plug in a standard stereo headphone without a mic., you will short the mic connection to ground. This may or may not cause issues. I remember seeing my Epic 4g Touch act strange when I tried to use my computer's headphones. Standard Ipad/IPhone/IPod headset should work okay. Or any headset meant for a smartphone. For the N7, push hard when you plug it in.

I feel your pain, imagine this.... I GOT MY NEXUS 7 CHRISTMAS, now after nearly 4 weeks, screen broke yesterday :c. I'm looking for a way to repair it.
Anyways I think it is a virus that youy might have... or also ASUS hardware...
Hope you find the solution in the near future.
